A kind of online condition control method and system
Technical field
The present invention relates to a kind of online condition control method and system, in the network process, dynamically the method and system of net state are gone up in control on particularly a kind of use pre-payment.
Background technology
Increase along with Internet (internet) traffic carrying capacity, the Internet broadband data service is also in development constantly, the sort of user in past opens broadband access must be over and done with by the operation way of operator's rewiring, the substitute is emerging broadband cell, be broadband user's natural formation, the user no longer needs operator's independent wiring, only need open port, the user uses a broadband number of the account can realize function of surfing the Net, has really realized the online of plug and play.
In order to enrich the mode of user's online, satisfy dissimilar users' use habit, also reduced the operation risk of operator simultaneously, pre-payment number of the account advantage convenient with it gradually, real time billing becomes the network access of user's first-selection.
At present on wide-band networking, mostly adopt authentication, authorization and accounting server (AAA Server, Authentication, Authorization and Accounting Server) as Radius server (RadiusServer) and arrowband/broadband access equipment (NAS/BAS, Network Access System/BroadbandAccess System) mutually interconnected by standard Radius (RFC2865, RFC2866), finish user's authentication; But because in standard Radius agreement, AAA only as the reciever of protocol message, receives the request of NAS/BAS, and responds; Finish authentification of user, mandate and charging, and can only issue the traffic carrying capacity (available duration via or utilizable flow) that the user can use in the authentication success response, charging process Radius charges to respond and only is used to respond the charging message that NAS/BAS reports; Therefore the user goes up to roll off the production line in the network process and has only NAS/BAS could control (user is initiatively rolled off the production line, available quantity be 0 to roll off the production line), and user or prolongation subscriber authorisation available traffic can't initiatively be nipped off by AAA or operator; If therefore user's supplementing with money also in line process can't free of discontinuities be used.
Fig. 1 is the schematic network structure under the Radius protocol technology, when prior art realizes on standard Radius, the structure chart of networking as shown in the figure, in network, comprise user terminal 101, access device NAS/BAS102, charge system AAA103, network Internet, wherein communicate by the Radius agreement at AAA and NAS/BAS.
Fig. 2 is the network work flow diagram under the Radius protocol technology, as shown in the figure, mainly comprises the steps: in the workflow of network
Step 201, user terminal send link layer protocol (PPP, the Point-to-Point Protocol) request of point-to-point to access device;
Step 202, access device send authentication request to the AAA charge system;
Step 203, AAA carry out authentication;
Step 204, AAA carry out budget;
Step 205, AAA send authentication response to access device;
Step 206, access device send the request of charging to AAA;
Step 207, AAA are to the access device response of chargeing;
Step 208, access device send the request of charging in renewal;
Step 209, AAA settle accounts;
Step 210, AAA ask to charge response to chargeing;
Step 211, user terminal send offline information;
Step 212, access device send the request of charging to AAA;
Step 213, AAA settle accounts;
Step 214, AAA are to the access device response of chargeing.
Wherein, in the prior art, have following characteristics: 1, in the user authentication process, AAA need be according to remaining sum and rate budget available traffic (available duration via or utilizable flow); 2, also need available traffic is handed down to NAS/BAS in the subscriber authorisation process, NAS/BAS controls the user according to the available traffic that receives and uses; 3, user's Intermediate Charging ICH and traffic carrying capacity of only user having been used of finish chargeing in line process settled accounts, and can't issue available traffic again; 4, the user has under two kinds of situations and can roll off the production line, and the one, the user is initiatively rolled off the production line (user disconnects connection), and another is that the available traffic of authorizing uses up.
By the implementing procedure of above-mentioned prior art and the restriction in their work, we are not difficult to find out that prior art has the following disadvantages:
1, user terminal AAA in line process can't initiatively nip off user terminal;
2, user terminal AAA in line process can't prolong the available traffic when authorizing, and the user can not be implemented in and supplement remaining sum in the line process with money, reaches uninterrupted online purpose so that the user can supplement with money;
3, since when authentication AAA need be according to user balance budget available duration via, and freeze user balance and pay, so the user can only have an application simultaneously to guarantee the service in the surf time section, can't one card for multiple uses.
In sum, prior art is because in standard Radius agreement, and AAA is only as the recipient of protocol message, the request of passive reception NAS/BAS, and responding, make AAA can not be flexibly initiatively the last net state of control user terminal.

The first message dispensing device 7031 when charge system 703 is received external command, sends first message to access device 702; Subscriber equipment 702 is connected according to the control of received first message content and user terminal 701.
Be that a COA message sending unit 70311 of zero COA message, the 2nd COA message sending unit 70312 that sends the COA message of new available traffic describe to transmission available traffic included in the first message dispensing device 7031 below.
When access device after user terminal sends connection request, obtain the authentication, expense budget, response of AAA after, keep being connected with user terminal, access device is when to receive traffic carrying capacity be zero COA message, with regard to being connected of disconnection and user terminal; When receiving the COA message of new available traffic, according to the be connected duration of the new available traffic maintenance in the message with user terminal.
Because a COA message sending unit has been arranged, if operator wishes to nip off the user, then issuing an available traffic by AAA is that 0 COA message is given access device NAS/BAS, as NAS/BAS after to receive available traffic be 0 COA message, can send out a COA response to AAA, send once more and finish charging message, and nip off the user, AAA receives the end charging message that NAS/BAS sends, and then the user is settled accounts, and stops user's online.
If Sorry, your ticket has not enough value for the online discovery of user, then can onlinely supplement with money, AAA is sent recharge request message, the user supplements back AAA with money and directly recharge amount is added in the user balance, lays equal stress on to take the family remaining sum and carry out budget; AAA is handed down to NAS/BAS to the new traffic carrying capacity used by COA message by the 2nd COA message sending unit, and NAS/BAS change user's available traffic reaches online prolongation user available traffic purpose; After NAS/BAS receives the COA message of new available traffic, can send out a COA response, and adjust user's available traffic to AAA.
Can also be in charge system by the new available traffic of total traffic segment assignments.Its effect is, in user authentication process, can make AAA not need to reserve whole remaining sums, and reservation procedure is placed on the charging stage, and segmentation is reserved; By the second message dispensing device message of not controlling available traffic (or be changed to maximum to available traffic) is issued NAS/BAS in the subscriber authorisation process, NAS and BAS do not need to control user's available traffic; After the user chargeed beginning, AAA carried out segmentation (allowing configuration) to user balance and reserves, and only reserves the part of user balance; AAA issues segmentation by the 2nd COA message sending unit and reserves the remaining sum available traffic to NAS/BAS, and NAS/BAS uses according to the available traffic control user who issues; AAA checks available traffic when each Intermediate Charging ICH message, if during metering period of available service quantity not sufficient (reporting the interval of Intermediate Charging ICH message), then reserve again, and issue COA message to NAS/BAS by the 2nd COA message sending unit once more; Because the whole remaining sums of user are not freezed in session of user, only reserve the part of blocked balance according to the cycle, therefore can a plurality of sessions reserve simultaneously, and do not influence mutually; Can guarantee also simultaneously that all sessions of user are simultaneously online under the enough situations of user balance.
The invention solves the problem that AAA under the standard Radius agreement can't ACTIVE CONTROL NAS/BAS as can be seen from inventive embodiments, with their in conjunction with after can realize that not only operator initiatively nips off the user, can also realize that the user is online and supplement uninterrupted use with money, onlinely come into force, also can realize user a plurality of sessions, i.e. one card for multiple uses simultaneously.
